![]() ![]() Close all the electronics by placing the cover on top of it and screwing it to the lid using M3 screws. Place the ballast and PCB on top of the lid using some double-sided tape and carefully route the cables to them. So this time I printed a holder and attached the OLED to it using pins. I have broken quite a few OLED displays while screwing them. Stick the reed switch on the inside of the front side of the lid and a small neodymium magnet on the inside of the drawer such that when the drawer is fully closed the reed switch and magnet lineup thus closing the contacts.Īttach the OLED display and rotary encoder to the front panel as shown. Insert the M3x4mm threaded inserts in the lid using a soldering iron. Stick the control panel to the control box using superglue as shown in the picture. The two clamps should be in a straight line or else the tube won't fit.Ĭover the inside portion of the enclosure using aluminum tape. Stick the clamps on the inside of the lid. I figured out how the code works and modified it to suit my need. Thanks to Henry Mane all the hard work of creating a menu was already done. The menu can be controlled using a rotary controller. With a press of a button, a high-energy beam of UVC (ultraviolet C) light is emitted from the specialized LEDs, effectively sanitizing surfaces without the use of chemicals. A menu will be created and displayed on an OLED display. CleanPod is an essential tool in protecting yourself against the invisible germs lurking on all the objects you touch at home or outside. The second one will be a Timer Mode wherein the lamp will be turned ON for a set amount of time. First will be Manual Mode wherein you have to manually turn OFF the lamp. Only UVA and UVB can reach the earths surface through ozone protection and clouds. A magnetic reed switch will be used as an extra step to safety such that the lamp will turn/remain ON only when/till the door is closed.Įverything will be controlled using an Arduino Nano. The experimental results show that the effective wavelength range of ultraviolet sterilization can be divided into four different bands,: UVA (400315nm), UVB (315 280nm), UVC (280200nm and vacuum ultraviolet (200 100nm). This will also help in reflecting the light evenly. I will be using aluminum tape to cover the inside of the enclosure where the light will hit. I'm not an expert on this so it is better to be safe. Since the lamp will be in an enclosure made up of plastic which may absorb most of the radiation and prevent it from reaching us, there is a slight chance of radiation leaking through it. One part is the region where the radiation will occur and the last part is the drawer which will hold the objects to be sterilized.Īs already stated, it is not a good idea for us to get exposed to UVC radiation frequently. The uppermost part houses all the electronics and a UVC lamp. Build a box of some kind and put the UVC lamp in it. Proceed only if you know what you are doing! You can direct its UV light to kill germs on nearly anything. This project involves working with AC mains electricity as well which can be lethal. Disclaimer: Overexposure to UVC radiation can cause permanent damage to skin and eyes.
